Thoughts on September 20:
Look at investment correctly, don't think about getting rich overnight, and blindly seek high returns.
The big pie has closed three consecutive big positive lines on the daily line, and the overall trend is very strong. As long as the bullish force does not show a significant decline, it is still possible to buy on dips. The 4-hour line is still dominated by bulls. Although the hourly line has fallen back, it can also be considered as a buildup before the force is exerted.
Short-term suggestions:
Big pie: 62500-62800 long, 64000-64500, guard 62300
Second pie: 2400-2430 long, 2500-2550, guard 2380
